Psychological symptoms following a road traffic accident should not be assumed, exaggerated or treated as an automatic companion to physical injury. They should be assessed with the same care as pain, restricted movement and physical function.
The symptoms do not always announce themselves.
A claimant experiencing travel fear may not use psychiatric language. They may say they have become a cautious driver, dislike busy roads or prefer somebody else to drive. Only further questioning reveals that they have stopped travelling alone, changed their route to work or experience panic when stationary traffic closes around them.
Other symptoms can be equally easy to miss. These include disrupted sleep, intrusive recollections, irritability, heightened alertness, low mood and avoidance of reminders of the accident. NICE identifies re-experiencing, avoidance, hyperarousal and functional impairment among the features that should be explored when post-traumatic stress is suspected. It also advises active monitoring where subthreshold symptoms are present within the first month following a traumatic event.
Not every frightened driver has a psychiatric disorder. Anxiety immediately after a collision may be an understandable and temporary reaction. The medico-legal question is whether the response persisted, became disproportionate and interfered with the claimant’s ordinary activities.
That requires more than asking, “Are you nervous in a car?”
Pain and fear can maintain one another.
The old division between a physical whiplash injury and an entirely separate psychological reaction is often artificial.
Pain can make the claimant feel vulnerable. A sudden neck movement while travelling may be interpreted as evidence that further damage is occurring. The claimant becomes tense, scans the road for danger and avoids movements or situations associated with discomfort. Reduced activity then contributes to physical deconditioning and reinforces the belief that the neck remains fragile.
The psychological literature on whiplash-associated disorders has repeatedly examined anxiety, travel anxiety, depression, fear avoidance, pain catastrophising and post-traumatic stress symptoms as factors associated with prolonged symptoms and poorer recovery. The evidence does not mean that psychological factors explain every persistent whiplash complaint. It does mean that a purely mechanical account may be incomplete.
This point is sometimes mishandled in reports. An expert identifies anxiety and then implies that the physical symptoms are not genuine. That does not follow. Pain, fear and avoidance may coexist and influence one another without any of them being fabricated.
Travel fear is not one diagnosis.
“Travel anxiety” is a description, not necessarily a diagnosis.
One claimant may feel mildly uneasy as a passenger but continue to travel. Another may avoid only motorways. A third may experience panic, intrusive memories and marked restriction across most forms of road travel.
The symptoms may form part of an adjustment disorder, a specific phobia, post-traumatic stress disorder or another anxiety presentation. In other cases, they remain below the threshold for a recognised disorder.
PTSD should not be used as a convenient label for every post-accident symptom. NICE refers to serious accidents as events that may be associated with PTSD, but diagnosis depends upon the nature of the exposure and the required pattern of symptoms and impairment.
The label matters because it affects treatment recommendations, prognosis and the level of expertise required. It also matters under the whiplash compensation framework in England and Wales.
“Minor psychological injury” has a particular legal meaning.
The whiplash tariff applies to qualifying whiplash injuries lasting no more than two years. It contains separate figures for whiplash alone and whiplash accompanied by minor psychological injury. An amended tariff applies to accidents occurring on or after 31 May 2025, while the earlier tariff continues to apply to accidents between 31 May 2021 and 30 May 2025.
Government guidance states that a minor psychological injury for tariff purposes is suffered on the same occasion as the physical whiplash injury, is secondary in significance to that injury and falls short of a diagnosed specific phobia or disorder. Examples given include low-level travel anxiety or occasional sleep disturbance.
The word “minor” should therefore not be applied merely because the psychological symptoms arose in a low-value claim. Nor is every reference to anxiety enough to justify the higher tariff.
A diagnosed specific phobia or another recognised disorder cannot simply be placed under the minor psychological injury heading without further analysis. Equally, low-level nervousness should not be inflated into a separate psychiatric condition because a diagnostic term appears more persuasive.
The medical evidence must describe what the claimant experiences and how it affects function.
The records rarely tell the whole story.
Contemporaneous records are important, but psychological symptoms are not always reported at the first GP appointment.
The claimant may initially be concerned about neck pain, medication or absence from work. They may regard fear of driving as normal and expect it to settle. Some do not seek treatment because they can avoid the problem by relying upon relatives or public transport.
A lack of early reporting weakens some cases, particularly where severe symptoms are later alleged. It does not decide causation by itself.
The expert should establish when the claimant first drove or travelled after the accident, what happened during that journey and whether avoidance increased or reduced over time. Practical detail is more informative than broad adjectives. Which roads are avoided? Can the claimant travel as a passenger? Have working hours, childcare arrangements or social activities changed? Is the restriction consistent with what is recorded elsewhere?
Alternative explanations must also be considered. A claimant may have experienced earlier driving anxiety, another collision, unrelated stress, pain from a different condition or a pre-existing anxiety disorder. The index accident may have caused a new condition, aggravated an existing vulnerability or made no material difference.
CPR Practice Direction 35 requires expert evidence to be independent and objective, to address material facts that may detract from the opinion and to remain within the expert’s field.
Referral should follow the evidence.
A primary reporting expert may be able to identify and describe short-lived shock, mild sleep disturbance or limited travel anxiety. More persistent, disabling or diagnostically uncertain symptoms may require evidence from a suitably qualified psychologist or psychiatrist.
Referral should not be automatic. Commissioning specialist evidence for every expression of nervousness adds cost without necessarily helping the court. The question is whether the psychological presentation is sufficiently complex or significant that the first expert cannot diagnose it, explain causation or provide a reliable prognosis.
Treatment recommendations should also match the presentation. Some early symptoms may settle with time and a gradual return to normal activity. Clinically important post-traumatic symptoms may require structured psychological treatment delivered by an appropriately trained practitioner. NICE recommends trauma-focused cognitive behavioural therapy for adults with PTSD or clinically important PTSD symptoms in the relevant circumstances and includes help to overcome avoidance within that treatment.
A report should not prescribe a standard block of therapy merely because the claimant mentions anxiety. It should explain what is being treated and why.
Psychological symptoms are hidden in whiplash claims only when nobody asks the next question. They should not be presumed from the accident, and they should not be dismissed because the physical injury appears modest.
A claimant who can turn their neck but cannot face the road may still have an unresolved injury. The expert’s task is to determine whether that restriction is a temporary fear, a minor psychological reaction or a recognised disorder, and to say so without stretching the evidence in either direction.
